Ingredients:

  • 2 (6 oz / 170g) Ahi tuna steaks
  • 2 tbsp white or black sesame seeds
  • 1/2 tsp kosher salt
  • 1/2 tsp freshly cracked black pepper
  • 1 tbsp avocado oil
  • 1 tbsp fresh lemon juice
  • 1 tbsp low-sodium soy sauce
  • 1 tsp toasted sesame oil
  • 1/2 tsp garlic powder

Instructions:

  1. Pat the tuna steaks completely dry on all sides using paper towels to ensure a proper sear.
  2. Mix sesame seeds, salt, and pepper on a flat plate; press each side of the tuna firmly into the mixture to form a crust.
  3. Heat a cast iron skillet over high heat with avocado oil until the oil shimmers and barely smokes.
  4. Sear the tuna for 45 to 60 seconds per side without moving the fish to ensure a crust forms.
  5. Using tongs, quickly sear the thin edges of the steak for 15 seconds each.
  6. Turn off the heat and immediately add lemon juice, soy sauce, toasted sesame oil, and garlic powder to the pan.
  7. Quickly flip the tuna in the glaze for 10 seconds, then remove to a cutting board.
  8. Let the tuna rest for 2 minutes, then slice into 1/2-inch thick pieces against the grain.
